There have long been threads of investigation into covert channels, and threads of investigation into anonymity, but these two closely related areas of information hiding have not been directly associated. This paper represents an initial inquiry into the relationship between covert channel capacity and anonymity, and poses more questions than it answers.(More)
OBJECTIVES Cohen's kappa coefficient is presently a standard tool for the analysis of agreement on a binary outcome between two tests. In view of the ubiquity of the use of sensitivity, specificity, raw agreement and kappa in clinical studies, clearly it is advantageous to have a useful analytic relation connecting these measures of agreement. METHODS We(More)
Prediction of life tables, which provide the most empirical information available about the statistical properties of aging, provides a rigorous test for any theory of aging as manifested at the organismic level of biological organization. For this purpose, a set of test tables for the wild boar (Sus scrofa), domestic sheep (Ovis aries), Dall sheep (Ovis(More)
We deduce an explicit representation for the coefficients in a finite expansion of a certain class of generalized hypergeometric functions that contain multiple pairs of numeratorial and denominatorial parameters differing by positive integers. The expansion alluded to is given in terms of these coefficients and hypergeometric functions of lower order.(More)
We show that a certain generalized beta function B(x; y; b) which reduces to Euler’s beta functions B(x; y) when its variable b vanishes and preserves symmetry in its parameters may be represented in terms of a nite number of well known higher transcendental functions except (possibly) in the case when one of its parameters is an integer and the other is(More)
